Ahmed Sameh is the Samuel D. Conte Professor of Computer Science. His current research interests include numerical linear algebra, and the design and performance analysis of parallel numerical algorithms needed in various science and engineering applications. He has served on the editorial boards of: IEEE Transactions on Computers, Computing, SIAM Journal on Scientific and Statistical Computing, Parallel Computing, Journal of Parallel and Distributed Computing, Computer Physics Communications, International Journal of High Speed Computing, Numerical Linear Algebra with Applications, IEEE Computing in Science and Engineering, and International Journal of Para llel Programming.

He joined Purdue in 1997 as Head of Computer Science, after being Head of Computer Science at the University of Minnesota, Minneapolis, and the holder of the William Norris Chair for Large-Scale Computing. He was also a faculty member at the Department of Computer Science at the University of Illinois at Urbana-Champaign, from 1968 to 1991, and 1992-93. During his tenure at Illinois, he served as an Associate Director, and Director, of the Center for Supercomputing Research and Development (CSRD).

He is a Fellow of ACM, IEEE, and AAAS, and a member of SIAM. He has also received the IEEE's 1999 Harry Goode Award for "seminal and influential work in parallel numerical algorithms".
